“…Therefore, ROS scavenging is most important defense mechanism to cope with stress condition in plants (Sharma et al, 2012; Baxter et al, 2014; Das and Roychoudhury, 2014). According to previous reports, exogenously Si can improve the ability of ROS scavenging by regulation of antioxidants enzyme activity (Torabi et al, 2015; Kim et al, 2016; Tripathi et al, 2017). Furthermore, regulation pattern across various crop plants is different depending upon the exposure time of the stress (Sharma et al, 2012; Kim et al, 2016).…”

“…According to Kim et al (2014c), the application of Si in rice plants under salinity significantly decreased the activities of non-enzymatic MDA and enzymatic antioxidants POD, PPO, and CAT on the other hands, Torabi et al (2015) observed that when they applied Si to borage plant, SOD activity was significantly increased in Si treatment but activity of CAT and APX was slightly decreased in Si application (Table 1). However, Shekari et al (in press) found that activities of CAT, APX, SOD, and POD were highly increased under Si application with NaCl to herbal Anethum graveolens plants.…”

Silicon Regulates Antioxidant Activities of Crop Plants under Abiotic-Induced Oxidative Stress: A Review

Silicon (Si) is the second most abundant element in soil, where its availability to plants can exhilarate to 10% of total dry weight of the plant. Si accumulation/transport occurs in the upward direction, and has been identified in several crop plants. Si application has been known to ameliorate plant growth and development during normal and stressful conditions over past two-decades. During abiotic (salinity, drought, thermal, and heavy metal etc) stress, one of the immediate responses by plant is the generation of reactive oxygen species (ROS), such as singlet oxygen (1O2), superoxide (O2−), hydrogen peroxide (H2O2), and hydroxyl radicals (OH), which cause severe damage to the cell structure, organelles, and functions. To alleviate and repair this damage, plants have developed a complex antioxidant system to maintain homeostasis through non-enzymatic (carotenoids, tocopherols, ascorbate, and glutathione) and enzymatic antioxidants [superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX)]. To this end, the exogenous application of Si has been found to induce stress tolerance by regulating the generation of ROS, reducing electrolytic leakage, and malondialdehyde (MDA) contents, and immobilizing and reducing the uptake of toxic ions like Na, under stressful conditions. However, the interaction of Si and plant antioxidant enzyme system remains poorly understood, and further in-depth analyses at the transcriptomic level are needed to understand the mechanisms responsible for the Si-mediated regulation of stress responses.

Iodine, silicon, and selenium are considered elements not essential for the metabolism of plants. However, these elements are vital for humans, and their presence as traces in food is beneficial. The use of I, Si, and Se in the fertilization programs of the plants allows, on the one hand, the mineral biofortification of the crops and, on the other hand, through mechanisms not yet fully understood, the production and accumulation of more antioxidants in the edible organs. This chapter provides an overview about the use of I, Si, and Se both for mineral biofortification and for the increase in the concentration of antioxidants in plants, with an emphasis on redox metabolism adjustments and antioxidant chemical species studied. The scope of the chapter is on horticultural species in the open field and under greenhouse or tunnels.

“…Zhang et al (2019) reported that application of biochar into soil could significantly improve the physicochemical properties of the soil under salt stress and greatly decrease exchangeable Na + and Cl − contents in the soil, proving a better soil environment for rice seedlings under salt stress. Additionally, the application of nitrogen and silicon could alleviate the adverse effects of salt stress and adjust the plants to perform normally by detoxifying the ROS (Siddiqui et al, 2010;Torabi et al, 2015). Athar et al (2008) reported that exogenously applied ascorbic acid alleviated the salt stress in wheat via improving photosynthetic capacity of wheat against salt-induced oxidative stress and maintaining ion homeostasis.…”

Hydrogen is an important molecule, exerting antioxidant ability in plants and animals through antioxidant enzymes, which can be dissolved in water. Previous studies have showed that application of hydrogen rich water (HRW), containing a high concentration of hydrogen, plays an important role in enhancing drought tolerance and alleviating the metal stress in plants. However, the effects of HRW on plant growth and physiological attributes in fragrant rice varieties under salt stress are still unclear. A pot experiment was conducted with two fragrant rice varieties i.e. Yuxiangyouzhan and Xiangyaxiangzhan to study the effects of HRW treatments i.e. foliar application of HRW (F-HRW) and irrigation application of HRW (I-HRW) on plant growth and physiological attributes under two NaCl levels (0 mmol L -1 and 150 mmol L -1 ). The results depicte d that, compared with without HRW treatment (CK), the F-HRW and I-HRW treatments significantly increased the dry weight per unit seedling height by 12.64% and 22.99%, while decreased the plant height by 3.92% and 2.97% respectively of two fragrant rice varieties under salt stress. Moreover, compared with CK treatment, the activities of peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) were enhanced by F-HRW and I-HRW treatments in NaCl-stressed fragrant rice cultivars and opposite results were observed for MDA content. In crux, our findings conclude that application of HRW modulates the plant growth and physiological attributes in salt-stressed fragrant rice cultivars.
